I've never been to an acl match very keen

Melb City need to increase the depth of their squad if they want a good run in the ACL.
8 ACL games in between A League games means squad rotation is going to be important.
But with so many players having left the club and only two significant signings, things are looking thin.
Yes the first 11 still looks strong but lose a few players to injury, like last year and the quality rapidly falls away.
